State of Minnesota, have invented certain new and useful Improvements inand Relating to Key Rings and the like,.of which the following is aspecification.

This lnventlon relates to certain 1mprovements in and relatlng to keyrings; and the objects and nature of the invention will be readilyu'nderstoodby those skilled in the art, in the light of the accompanyingdrawings and specificationsf-illustrating what I now believe to be thepreferred embodiments or mechanical expressions of my invention fromamong other forms, constructions and arrangements within the spirit andscope thereof.

Theobjeet ofthis invention is to rovide certain improvements in keyrings andthe like, with the end in view of increasing thee'fficiency'and ease with which keys may be attached and detached. v I

A further object of this invention is to provide such improvements andchanges in the design and construction of key rings that will in themanufacture of the same obviate all operations of swaging, forging, orof in any manner changing the form of the cross section of the stockfrom which they are made.

A further object of this invention is to" provide such improvements andchanges in the design. and construction of *key rings as will allow ofthe use of such standard material in its manufacture as to obviate Jalltempering and finishing forming operation.

A further object of this inventionfislto provide certain improveanentsin, the con SillUOtlOllOf key';r1ngs whereby the customs ary thumb-nailmethod of attaching and de same and the fre quentinjuries ar slng from,said method may taching keys from tie be eliminated.

With these and other objects in view, my,

invention consists in certain novel features in construction andincombination and a1:-

rangements as. more fully and particularly tion, 1 and nto thereceivlngspace, 1, as

set forth and specified hereafter.

Referring to the accompanying drawings: Fig. 1 is aside view showing thering with a key attached.

Fig. 2 is an edge view showing'thering with key attached.

processes after the] r 7 p 2 of the kev,.2, as'shown ln Fig. 4. The

drawings is manufactured from a single piece of commercial 1 sp1'ingtempered" and polished round wire forming approximately two completecircles orturns and is at a point intermediate its ends offseta distanceequal to the diameter'of theiwire from which the ring is made, formingan oblique portion, 1 1

The extremeend of the wire on thereceiving side of the ringis formedwith a laterally projectingarch, 1 forming the receiv- I '75 mg space,1, and also with an inward curve of a sufiiciently reduced radius toadmlt of the extreme end, 1 .of the arched portion passing nwardly oftheobhque POIt1011,. 1 -when,the curved portion, 1", is compressed bypassing keys having .exceptionally'small openings in their. heads,around thering,

' "Figures 3, 4 5 and 6 are views showing the I I l i ring with the keyinfthe different stagesof which is necessary when securingadditionalkeys tea ring with a key of the above description attached thereto.

The opposite end of thewireulies parallel and concentric with the mainbody of the ring and its extreme end, 1 abuts with the oblique.portion,1

To secure the key: 2 to the ring 1, the edge of the ringed end, or head,2 of the key is .placed in the key receiving space, 1, of the r ng,asshown in Fig, 3, and is then pressed arched'portion, 1 passes throughthe eye,

direction of -the key; is then reversed as shown in Fig. 5, and 1s movedcompletely ar'oundthe ring, as shown in 6, until it passesout from underthe discharging end of the ring 1, and assumes the position shown inFigures 1 and 2, key secured to theringl which show thedownwarduntilzthe extreme end, 1, of the To removepthefkey, the coils-ofthe key ring" are expanded'sufiiciently'to allow the ringedportion, 2 ofthe key, 2, to pass under the extreme-end, 1 of the arched por shown inFigures 7 and 8 It is then moved completely around the ring into the'posi ingend, 1".

It is evident that various changes, inodifications and variations mightbe resorted to wlthout departing from the splrit and scope of myinvention, therefore, 1 do not Wish to limit myself to the exactdisclosure thereof;

What I claim is said Wire, a laterally projecting arched per tion at oneend of sa d Wlre having ts terminus lnside of said coil and hav ng an1n-Ward curvature of a suficiently reduced radiusto admit of its extremeend passing inwardly of the oblique portion when compressed.

2. In a key ring, a coil of approximately two complete turns, producedfrom a single piece of Wire of a uniform cross section throughout itsentire length and having a laterally projecting arched portion at oneend of said Wire having its terminus inside of said coil and having aninward curvature of a sufiiciently reduced radius to admit of itsextreme end passing iiut 'ardly of said coil.
